Focused metamorph. Version 1 used Alternate Form and Minions, but AF wasn't quite working for me and too-versatile Minions were frowned on by staff. Version 2 went with Metamorph, with first four forms (human, BeatClank, SwarmClank, ElectroClank) and then dropping ElectroClank, but even that was deemed too versatile by staff. Version 3 is a simpler battlesuit, which works fine, but I really prefer the idea of turning into Clank, not putting it on. Version 4 goes back to Metamorph, but just two forms.
